There are a lot of things-every mention-every discovery be it Edward murphy or Thomas Edison after failling a thousen times - every body has gone up the bolling limit. Pushing them selves up. Nothing over happen in life to come push you up to your limits, to be able to test your limits ? It is something you need to get up your self and do? It is more gratifying if you have control over them. Insted of sitting there, you want to do something special - something that will bring your grater potential in the forefront rather than life giving you ups and down. You would probably suceed even that but when you have the control, it is more gratifying, more satisfying, it is more sucessful.
